| Re: How would I repair my plastic splash guards? There is this stuff called Pro-Form Stage II. A lot of people in the tuner scene use it when molding things to their cars such as lips, skirts, etc. It's pricey though...comes in around $53 CDN, but the stuff is absolutely fantastic. After it dries, you can sand it to shape as well.
There's other options but this was the first thing that came to my head. |
